Abstract
Photocathodes for hydrogen evolution from water were made by electrodeposition of Ni−Mo layers on NiFe2O4 substrates, deposited by spin coating on F:SnO2‐glass. Analysis confirmed the formation of two separate layers, without significant reduction of NiFe2O4. Bare NiFe2O4 was found to be unstable under alkaline conditions during (photo)electrochemistry. To improve the
